🔍 Key Concepts

• Explosion relief valves on internal combustion engines used in marine service • How the number of cylinders and bore size affect safety requirements • Relevant requirements in 46 CFR for crankcase explosion relief on engines

💭 Think About

• Consider why larger-bore, multi-cylinder inline engines present a higher explosion risk in the crankcase. • Think about whether regulations usually say a fixed number of valves, or a minimum based on engine size and configuration. • Ask yourself: if an engine has more than eight cylinders, would safety rules likely require fewer, exactly, or at least a certain number of relief valves?

✅ Before You Answer

• Check what 46 CFR says about minimum crankcase explosion relief area per cylinder or per engine side. • Verify whether regulations describe the requirement as a fixed count (e.g., two or three) or as at least a certain number that can increase with size. • Confirm that engines above a certain bore size (e.g., 8 5/8 in or 9 in) do in fact require explosion relief valves, rather than being exempt.
